KACOLIRIS, Federico P. et al. Ampliación del conocimiento sobre uso de hábitat en Liolaemus multimaculatus, sitios de fuga. Cuad. herpetol. [online]. 2011, vol.25, n.1, pp.5-10. ISSN 1852-5768.

The knowledge about spatial preferences in animals represents the first stage to understand the interactions between the organisms and its environment. The sand dune lizard (Liolaemus multimaculatus) is a species highly adapted to live in the sand. The goal of this work was to study the habitat use in different moments/situation during its period of activity, in order to obtain a more understanding about spatial preferences in this species. Models based on the use vs availability criterion were applied in order to assess the preferences for sites used as refuge and to compare those sites with perch sites. The models shows differences between use and availability and also differences between perch sites and refuge sites were observed. Results shows that this species used a great diversity of microhábitats with a high reject for microhabitats without vegetation cover. The conservation of good habitats for this species must consider both kinds of microhábitats, those used for thermoregulation and feed and those others used for refuge.
